摘要:
A seat reclining apparatus is provided with a neutral position returning means which holds a link lever at a forward reclining operating position, and releases the holding of the link lever in the case that a seat back is shifted from a forward reclined position side to a neutral position within a reclining range. The neutral position returning means shifts a cam plate by a spring in such a manner as to hole the position of the link lever at a lever rotating position while the link lever rotates a releasing lever fixed to a center shaft of a reclining lock mechanism together therewith so as to release a lock of the reclining lock mechanism, and shifts the cam plate to an original position against the spring by a cam releasing means so as to return the link lever to an original position, in the case that the forward reclining seat back 3 is shifted to the neutral position.

摘要:
To provide initiators in two components having no discoloring after polymerization and excellent polymerization-curability under the existence of water, and provide a polymerizable composition using the initiators in two components. The initiators in two components is for polymerizing and curing a (meth)acrylate compound, and the initiator includes (a) a peroxide being compatible or soluble with water, (b) an aromatic sulfinic acid compound, (c) a tert-amine compound, and (d) water. The polymerizable composition uses the initiators in two components. Particularly, preferably, the polymerizable composition includes a first component and a second component. The first component comprising (a) a peroxide being compatible or soluble with water, and a (meth)acrylate compound, and the second component includes (b) an aromatic sulfinic acid compound, (c) a tert-amine compound, and (d) water.

摘要:
To provide a polymerizable composition having more excellent preservation stability of pastes than a conventional composition using a combination of a copper compound, cumene hydroperoxide, and N-acetylthiourea, and having a polymerization curing time which does not change with time, that is, does not delay or quicken from a time set for a product even though the composition is stored, the polymerizable composition includes a first paste and a second paste, wherein the first paste includes a polymer of α-β unsaturated monocarboxylic acid or α-β unsaturated dicarboxylic acid, water, and a hydroperoxide as a peroxide, and the second paste includes a (meth)acrylate compound not having an acid group, fluoroaluminosilicate glass powder, a thiourea derivative as a reducing material, and a vanadium compound as a polumerization accelerator.
摘要:
To separate a catalyst for polymerizing a monomer contained in a liquid or paste dental composition containing at least a monomer, such as a dental resin cement, an autopolymerizing dental resin or a resin-reinforced dental glass ionomer cement, from the liquid or paste dental composition to thereby improve storage stability of the dental composition and reduce number of division of the dental composition, an extrusion nozzle for a dental composition mounted on one end of an extruder for extruding a liquid or paste dental composition containing at least a monomer, the extrusion nozzle contains a catalyst for polymerizing the monomer contained in the dental composition during extrusion, and the catalyst is attached to an inner wall of an extruding channel of the extrusion nozzle.
